3. Setup
3.1 Winding the Watch
The Spinnaker Spence 300 is equipped with a Japanese Miyota 9039 automatic movement. This movement is powered by the natural motion of your wrist. If the watch has stopped or has not been worn for an extended period, it may require manual winding to initiate operation.
- Ensure the crown is in the fully pushed-in position (Position 0).
- Rotate the crown clockwise approximately 20-30 times. This will provide sufficient power reserve to start the watch.
- The watch will continue to wind automatically as you wear it.
3.2 Setting the Time
- Unscrew the crown by turning it counter-clockwise until it springs out to Position 1.
- Gently pull the crown out to Position 2. The second hand will stop (hacking feature).
- Rotate the crown to set the hour and minute hands to the desired time.
- Once the time is set, push the crown back into Position 1.
- Screw the crown back in clockwise firmly against the case to ensure water resistance.
3.3 Adjusting the Bracelet
The stainless steel bracelet can be adjusted by adding or removing links. This procedure typically requires specialized tools and is best performed by a qualified watchmaker or jeweler to avoid damage. The bracelet features a fold-over buckle with a push-button release for secure fastening.
4. Operating the Watch
4.1 Automatic Movement
Your watch is powered by an automatic mechanical movement. It does not require a battery. The movement of your wrist causes an oscillating weight inside the watch to rotate, winding the mainspring and storing energy. When fully wound, the watch has a power reserve that allows it to run for a certain period (typically 40+ hours) when not worn.
4.2 Unidirectional Bezel
The Spence 300 features a unidirectional rotating bezel, which is a common tool in dive watches for timing events. It rotates only counter-clockwise to prevent accidental lengthening of timed intervals, a critical safety feature for divers.
- To use, align the triangle marker on the bezel with the minute hand at the start of the event you wish to time.
- Read the elapsed time by observing the minute hand's position against the bezel's markings.
4.3 Water Resistance
This watch is water resistant to 300 meters (1000 feet). This rating makes it suitable for professional marine activity and serious surface water sports, but not saturation diving. Always ensure the crown is fully screwed down before exposing the watch to water.
- Important: Do not operate the crown or pushers (if present on other models) while the watch is wet or submerged.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.
5. Maintenance
5.1 Cleaning
To maintain the appearance of your watch:
- Wipe the case and bracelet with a soft, dry cloth regularly.
- For stubborn dirt, use a soft brush and mild soapy water, then rinse thoroughly with fresh water and dry. Ensure the crown is screwed down before using water.
- Avoid using harsh chemicals or abrasive materials, as these can damage the watch's finish.
5.2 General Care
- Avoid Extreme Temperatures: Do not expose your watch to sudden temperature changes or extreme heat/cold.
- Avoid Shocks: While durable, severe impacts can damage the internal movement.
- Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, certain electronic devices) as they can affect timekeeping accuracy.
- Service: Mechanical watches benefit from periodic servicing (typically every 3-5 years) by a qualified watchmaker to ensure continued accuracy and water resistance.
6. Troubleshooting
6.1 Watch Not Running
- Insufficient Power Reserve: If the watch has not been worn or manually wound, it may have run out of power. Manually wind the watch as described in Section 3.1.
- Crown Position: Ensure the crown is fully pushed in and screwed down. If it's pulled out, the watch will not run.
6.2 Inaccurate Timekeeping
- Magnetic Interference: Exposure to strong magnetic fields can affect accuracy. If you suspect this, a watchmaker can demagnetize the watch.
- Power Reserve: An insufficient power reserve can lead to erratic timekeeping. Ensure the watch is adequately wound.
- Service Required: If accuracy issues persist, the movement may require servicing.
6.3 Condensation Under Crystal
If you notice condensation under the crystal, this indicates a breach in water resistance. Immediately contact customer support or a qualified watchmaker for inspection and repair to prevent further damage to the movement.
